You don't need to do anything special to use /vicepb and /vicepc. Just
create volumes on them. (Use "vos listpart $server" to figure out what
partitions are there, maybe you need to restart the AFS servers using
"bos restart $server -all" if you added the partitions after starting
the server processes)

There cannot be more than one cell per server. You seem to misunderstand
the cell / server / partition concept.

Cell: An administrative domain. Or: An authentication domain. Usually
consists of one or more servers.
Server: Belongs to a cell. Contains data belonging to a cell
(authentication / user+group / file data)
Partition: A container for volumes. Resides on a server.  There might be
more than one partition per server.
Volume: A container for files + directories + ACLs. A volume is
basically a name, a number and a quota (max. size). A volume is stored
in a partition. It might have readonly clones on other servers.

AFAIK there is no out-of-the-box method of hot-syncing two AFS file
servers. At least there is no special infrastructure in OpenAFS. 

HTH! Tino.
